Atypical Presentations of Common Disorders Flashcards
Atypical presentation of illness:
an older adult presents with a disease
state missing some of the traditional core
features of the illness usually seen in
younger patients
Atypical presentations Usually include one of 3 features:
- VAGUE presentation of illness
- ALTERED presentation of illness
- NON-PRESENTATION of illness
Risk Factors for atypical presentations
- Increasing age
- esp. 85 years +
- Multiple medical conditions
- multimorbidity
- Multiple medications
- polypharmacy
- Cognitive or functional impairment
Acute Coronary Syndrome etiology
- atherosclerosis of coronary arteries → plaque
rupture → coronary artery occlusion → ischemia
→ infarction
Acute Coronary Syndrome - atypical presentation
- mild or a complete absence of pain
- can occur in the absence of dyspnea
- new-onset fatigue, dizziness, or confusion
- Shortness of breath is more common than chest pain
- Decreased functional status
Acute Coronary Syndrome diagnosis
- Electrocardiogram (ECG) &/or positive biomarkers with findings of ST-segment
depression - Prominent T-wave inversion
- Elevated troponin levels
- Absence of ST-segment elevation on ECG
Acute Coronary Syndrome - Unique Management Considerations for the Elderly (>75 years old)
- Evaluate for therapeutic interventions in a similar manner as younger patients
- Management decisions should not be based solely on chronologic age but on:
- general health
- functional & cognitive status
- comorbidities
- life expectancy
- patient preferences & goals
- Adjust dosing (weight & est. Cr clearance) of medications
______ preferred
over _____ to reduce cardiovascular
disease events, readmission, &
improve survival rates in the elderly with ACS
Coronary artery bypass graft ; percutaneous coronary intervention
Pneumonia epidemiology
- Top 3 cause of death worldwide
- 2.225 million primary care visits annually in the USA
- 30-day mortality ~10% among patients > 65 years old hospitalized for pneumonia in
USA
Etiology of pneumonia in elderly
- Most common causes of
community-acquired
pneumonia - Respiratory viruses (influenza A & B, rhinovirus, corona virus human metapneumovirus, respiratory syncytial virus, parainfluenza, & adenovirus)
- Streptococcus pneumoniae
- Mycoplasma pneumoniae
- Haemophilus influenzae
- Chlamydia pneumoniae
- Legionella species
- Staphylococcus aureus
- Gram-negative bacilli
Pneumonia - atypical presentation
- May present with:
- weakness
- functional decline
- cognitive impairment or
change in mental status
Pneumonia diagnosis
- Tachypnea with or without shortness of breath → Most reliable sign
- Cough
- Fever
- Sputum production
- Pleuritic chest pain
- Rales or bronchial breath sounds on lung examination
- Infiltrate on chest x-ray or other imaging required for diagnosis
What is a requirement of diagnosis for pneumonia?
Infiltrate on chest x-ray or other imaging required for diagnosis
Pneumonia management
- Comorbidities will likely necessitate
in-patient management - Common first line agents
- amoxicillin/clavulanate cefpodoxime or cefuroxime AND a macrolide OR doxycycline
- levofloxacin (Levaquin®)
- moxifloxacin (Avelox®)
- Early mobilization
Unique Management
Considerations for the Elderly
* Comorbidities
* Polypharmacy
Complications of pneumonia
- Effusion & empyema
- Lung abscess (especially aspiration pneumonia)
- Bacteremia (esp.
Streptococcus pneumoniae pneumonia) - Sepsis
- cardiac complications (new or worsening heart failure, cardiac
arrhythmia, or MI) - ↑ risk of DVT & PE
Hyperthyroidism etiology
- Most common causes
- Graves disease
- toxic thyroid adenoma
- toxic multinodular goiter
Hyperthyroidism - Atypical Clinical
Presentation
- Classic signs
- tremor, irritability, &
nervousness - Often absent in the elderly
- Likely signs in the elderly
- Tachycardia
- Fatigue
- Weight loss
Hyperthyroidism diagnoisis
- Clinical exam
- 20% of patients will NOT have an enlarged gland or palpable nodule
- Ophthalmic signs are frequently absent
- Blood tests
- TSH
- T4 & T3
- Thyroid peroxidase antibodies
- Imaging
- Thyroid scintigraphy
- Radioactive iodine uptake
Hyperthyroidism management
- Treatment of hyperthyroidism
usually depends on underlying
cause - Antithyroid medications,
radioactive iodine, or
thyroidectomy - Beta blockers for symptomatic
thyrotoxicosis - Subclinical hyperthyroidism,
consider treatment in patients at
risk for complications or with
symptoms
Unique Management Considerations
for the Elderly for hyperthyroidism
- Strongly consider treatment if:
- age ≥ 65 years
- postmenopausal women not on
estrogens or bisphosphonates - cardiac risk factors
- heart disease
- osteoporosis
- hyperthyroid symptoms
